Slow cooker Puerto Rican black beans with sofrito and cilantro

In Puerto Rico, sofrito seldom contains tomato; it's a green condiment, called recaito. The red sofrito, more common in Cuba, is the one I prefer, and my homemade recipe is a combination of the two. This sofrito recipe makes 2 cups; you'll have some left over, to use in soups and stews. Serves 6, as a main course with rice.
